Starbucks is introducing its Starbucks Card mobile application across the country. It enables customers to start the app, hold up a barcode on the screen to a scanner in the store, which then automatically deducts money from the customer’s Starbucks Card account in exchange for his or her favorite beverage.

The application supports the iPhone, iPod touch, and a number of BlackBerry models.

“Today, one in five Starbucks transactions is made using a Starbucks Card and mobile payment will extend the way our customers experience and use their Starbucks Card,” said Brady Brewer, vice president Starbucks Card and Brand Loyalty.
